The methodology followed in the various units is the same with the one described in the introductory page of the project “Encyclopaedia of the Hellenic World”. However, given the fact that each geographical area under examination has its own peculiarities, we considered necessary to point out the methodological elements that characterize each one of them.

With the term “Black Sea” we indicate, for the purposes of this project, the geographical area of the coasts of the Black Sea covering a zone of approximately 100 kilometres from the coast. This means that the cities of the coast of Northern Turkey are included both in this volume of EHW and in the one about Asia Minor. The creation of an autonomous volume of EHW about the coasts of the Black Sea was deemed necessary, since the historical and cultural character of the area incorporates them in a network of settlements and areas with close relations among them.
